Our Customers love Cortex,
we thought we'd share what they are saying.


Kim & Jeffrey Cage

S/V As You Wish (Lagoon 440)

Salem, OR, USA

"Still learning about and loving my Cortex. Enough so that two sail mates are purchasing theirs own now. 😉"



Bruce Toal

S/V Wild Orchid (Beneteau 58)


"Anchor Watch with Cortex Onboard and Cortex Monitor is great! Especially love the scatter plot of positions, since I can never remember to hit the anchor down when I should so the scatter plot helps me refine my anchor position. I am enjoying the unit and two handests! Looking forward to all the new improvements ahead."



Jason & Monica

Breathe (Manta 40 Catamaran)

Lighthouse Point, FL, USA

"The Vesper Cortex is truly a multi-tasking workhorse. If you don’t currently have a Class B AIS transponder and DSC VHF, the decision is easy, as the dollar value is easy to calculate. For us, adding AIS, and having the ability for 1 button ship-to-ship communications was great. The added bonuses of location geo-fencing, excellent anchor watch programming, built-in cellular reporting, the ability to review and control ship systems, made the decision a must have for us."
